Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Most of the mass and all of the positive charge of an atom is in the nucleus. Most of an atom is empty space, (a vacuum). In 1897, ...

Niels Bohr's Nobel Lecture on December 11, 1922, titled The Structure of the Atom, is one of the most significant contributions to our understanding of atomic structure and quantum mechanics. This ...

Niels Bohr was one of the foremost scientists of modern physics, best known for his substantial contributions to quantum theory and his Nobel Prize-winning research on the structure of atoms. Born in ...

One hundred years after Niels Bohr published his model of the atom, a special issue of Nature explores its legacy — and how much there is still to learn about atomic structure. July 1913 saw Danish ...

Born in 1885 to Christian Bohr – a professor of physiology – and Ellen Adler Bohr in Copenhagen, Denmark, Niels Bohr made numerous contributions to the field of physics over the course of his life, up ...

THE beautiful conception which inspires and co-ordinates practically the whole of modern atomic physics is the atomic model of Rutherford and Bohr. Its essential feature-the nucleus-was first put ...

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly ...
